Specification of Letters Patent.

Application filed March 23, 1921. Serial No. 454,949.

To all whom it may GONCGTIL.

Be it known that l, EDWIN L. RoBiNsoN, a citizen of the United States, residing at li rovidence, in the county of Providence and State of Rhode Island, have invented a new and useful Swivel for Natch Chains and the like, of which the following a spe iiication.

T he purpose of my invention is to provide a swivel for watch chains and the like in which the tongue controlling spring is en tirely concealed within the body oi the swivel and the pin on which the tongue is commonly pivoted is dispensed with.

To these endsmy invention consists in th new and novel construction, combination and arrangement of parts hereinafter described and illustrated in the accompanying drawings, in which,-

Figure l is an elevation of a swivel embodying my invention. t

Figure 2 is a similar view of the same partly in section.

Figure 3 is a view of a V-shaped spring.

Figure d is a transverse section of the cap which conceals the spring, and on which the swivel tongue is fulcrumed.

Figure 5 is a bottom view 0t said cap, with the hook and tongue shown in cross section.

Figure 6 is a longitudinal section of the upper portion of the swivel body and of the tongue of the swivel hook, showing a coiled wire spring disposed in said body in en gagement with the tongue.

Figure 7 is a view of the coiled spring.

Figure 8 is a bottom view oi the body of the well known form of swivel body. showing the hook and tongue in cross section and the tongue controlling spring disposed between them.

Figure 9 shows details of the spring engaged end of the tongue.

Like reference letters and numerals indicate like parts where they occur in the several views.

In the drawings: 1 represents the chambered body of the swivel. which may be of any exterior conformation, ornamented or plain.

l/Vithin the chamber of said body is a vertically disposed spring arranged and adapted to be connected at one end with the upper end of the swivel latch or tongue to control the lateral movements of the latter. While said spring may be or any term 1 have for purposes of illustration shown in Figs. 2 and a two-arm V-shaped spring, as 2, and in Figs. 6, "i' and 9 another form of two-arm spring, as 3. Both of which may be formed or wire.

' The chambered portion of the swivel body is open at its lower end (Fig. 6). On its upper end rotatably is mounted in the well known manner the ring 5.

The lower open end of said chambered body is tightly closed by an immovable cupshaped cap 6 (Fig. l) which is provided in its face near one side with a perforation 8. at the'opposite side of said cap face and in alinement with said perforation is rigidly secured one end of the swivel hook or loop 7 (Fig. 5).

The upper end 9 of the tongue of the swivel hook is swaged or otherwisethinned, and is near its upper end pierced as at 11, to receive the end of the controlling spring (Figs. 2 and 9). Said tongue is further provided on its inner edge with a laterally directed notch 10 which engages with the edge of the perforation 8 of the cap 6 which thereby .SI'VQS a fulcrum for said tongue (Figs. 2. 5 and 9).

The hook 7 being secured to the cap 6 and the tongue 4: fulcrumed on said the latter is passed over the open end of the charm bored body 1 and swaged immovably there on thereby closing said open end and concealing the spring (Figs. 1 and 2).

I have thus provided an eliicient and. dura ble swivel for watch chains and the like in which the swivel. body is closed at one end. the swivel hook tongue fulcrumed on said closed end for oscillating movement as controlled by a spring concealed within said swivel body. Such spring being preferably of wire. may be of any form.

I claim as my invention, and desire to secure by Letters Patent:

1. A swivel, for watch chains and the like comprising a chambered body member open at one end and closed atthe opposite end. a ring rotatably mounted on said, closed end. a laterally acting spring vertically disposed in said chambered body, a cup-shaped cap immovably secured over and closing said open end of said body member and provided in its face near one side with a perforation. a swivel hook consisting of a loop member and a latch member, one end of said loop member secured to said cap face in alinement with said perforatlon, and the upper end of said latch member extending through sald perforation into said'chambered body memher and provided with a laterally directed notch in its inner edge engaging said c-apiat oneside of said perforation whereby said latch is held in operative position and fulcrumed on said cap for oscillating movements to open and close the swivel hook, and also provided withmeans for operatively connecting the upper end of said latch with said spring 2. In a swivel for Watch'chains and the likeithe combination of a hollow body member open at one end, a cap immovably secured over and closing said open end and havm'g 1n'1ts face near one side a perforation, a swivel hook consisting of a loop member and a latch nien'rb'er, one end of said loop member rigidlysecured'to the face of saidcap in alinement with said perforation, and said latch member protruding througn' said perforation into "said body member and provided in its edge with a laterally directed open end and provided near one side of its face with a perforation, a two'arm spring vertically disposed Within said hollow body, the combination With said parts of a hook member consisting of a loop member se cured at one end to the face of said cap in alinement with said perforation, and a latch member provided in one edge With a laterally directed notch arranged and adapted on theinsertion of said latch through said perforation to engage said cap to thereby hold said latch in operative position fulcrumed on said cap for oscillating movemen'ts of said latch, and means for operatively connecting said latch member with onearm of said spring.

at: In a swivel for watch chains and the like having a hollow body member, a latch controlling spring disposed therein, and a tap immovably secured on one endof said bodymember andhaving in its face near one side a perforation, the combination with said'parts of a=hoo'k member consisting of a loop portion secured at one end'to the face of said cap in alinement with said perforation and a latch member operatively connected to said spring and'provided in one edge with a laterally directed notch arranged and adapted to holdsaid latch in op'erativeposition' in said perforation fulcrumed on said cap.
